Cannot install python3-saml due to xmlsec in Docker

[TheDataDexter]

Hi there,

Running into a problem when building a Dockerfile. It seems to have to do with the underlying package xmlsec. I've tried several versions and still running into the problem

Similar issue to: #318

Build command:

ARG PYTHON_VERSION=3.10-slim-bullseye

# define an alias for the specfic python version used in this file.
FROM --platform=linux/amd64 python:${PYTHON_VERSION} as python
RUN apt-get update && apt-get install --no-install-recommends -y \
  libxmlsec1 libxmlsec1-dev libxml2 pkg-config

# Install pipenv
RUN pip install -U pip
RUN pip install xmlsec==1.3.13
# Python build stage
FROM python as python-build-stage

# Install apt packages
RUN apt-get update && apt-get install --no-install-recommends -y \
  # dependencies for building Python packages
  build-essential \
  # psycopg2 dependencies
  libpq-dev \
  # Translations dependencies
  gettext

# Requirements are installed here to ensure they will be cached.
COPY ./requirements .

# Create Python Dependency and Sub-Dependency Wheels.
RUN pip wheel --wheel-dir /usr/src/app/wheels --verbose \
  -r dev.txt

try this:

apt install build-essential pkg-config libxml2-dev libxmlsec1-dev libxmlsec1-openssl libpython3.11-dev

Change libpython3.11-dev to whatever version of python you are using.

also, you need to install it, before installing xmlsec ... move it above this line
RUN pip install xmlsec==1.3.13
first install apt packages, then pip
